A UA dipstick semi-quantifies which components?

• A. Only glucose and ketones
• B. Only pH and specific gravity
• C. It semi-quantifies multiple components including protein, glucose, ketones, pH, and specific gravity
• D. It does not quantify any components

Answer: (C)

The main idea is that a urine dipstick provides semi-quantitative estimates for several urine constituents, not exact measurements for a single item. Each reagent pad on the strip produces a color change that corresponds to approximate concentration ranges, so you get a quick, multi-analyte snapshot. Protein, glucose, ketones, pH, and specific gravity are all read on color scales that yield semi-quantitative results (negative, trace, 1+, 2+, etc.), giving a practical sense of how concentrated the urine is and whether these key constituents are present at abnormal levels. This is why the option stating it semi-quantifies multiple components including protein, glucose, ketones, pH, and specific gravity fits best. Other possibilities would either limit to only one or two analytes or claim there’s no quantification, which isn’t accurate because several components are read semi-quantitatively on the dipstick.
